Wrapper

public Wrapper(BaseRestHandler delegate)

Method Details

getName

public String getName()

Specified by:

getName in class BaseRestHandler

Returns:

the name of this handler. The name should be human readable and should describe the action that will performed when this API is called. This name is used in the response to the RestNodesUsageAction.

routes

public List<RestHandler.Route> routes()

Description copied from class: BaseRestHandler

The list of RestHandler.Routes that this RestHandler is responsible for handling.

Specified by:

routes in interface RestHandler

Specified by:

routes in class BaseRestHandler

prepareRequest

protected BaseRestHandler.RestChannelConsumer prepareRequest(RestRequest request,
 NodeClient client)
                                                      throws IOException

Description copied from class: BaseRestHandler

Prepare the request for execution. Implementations should consume all request params before returning the runnable for actual execution. Unconsumed params will immediately terminate execution of the request. However, some params are only used in processing the response; implementations can override BaseRestHandler.responseParams() to indicate such params.

Specified by:

prepareRequest in class BaseRestHandler

Parameters:

request - the request to execute

client - client for executing actions on the local node

Returns:

the action to execute

Throws:

IOException - if an I/O exception occurred parsing the request and preparing for execution

responseParams

protected Set<String> responseParams()

Description copied from class: BaseRestHandler

Parameters used for controlling the response and thus might not be consumed during preparation of the request execution in BaseRestHandler.prepareRequest(RestRequest, NodeClient).

Overrides:

responseParams in class BaseRestHandler

Returns:

a set of parameters used to control the response and thus should not trip strict URL parameter checks.

canTripCircuitBreaker

public boolean canTripCircuitBreaker()

supportsContentStream

public boolean supportsContentStream()

Description copied from interface: RestHandler

Indicates if the RestHandler supports content as a stream. A stream would be multiple objects delineated by XContent.streamSeparator(). If a handler returns true this will affect the types of content that can be sent to this endpoint.

allowsUnsafeBuffers

public boolean allowsUnsafeBuffers()

Description copied from interface: RestHandler

Indicates if the RestHandler supports working with pooled buffers. If the request handler will not escape the return RestRequest.content() or any buffers extracted from it then there is no need to make a copies of any pooled buffers in the RestRequest instance before passing a request to this handler. If this instance does not support pooled/unsafe buffers RestRequest.ensureSafeBuffers() should be called on any request before passing it to RestHandler.handleRequest(org.elasticsearch.rest.RestRequest, org.elasticsearch.rest.RestChannel, org.elasticsearch.client.node.NodeClient).

Returns:

true iff the handler supports requests that make use of pooled buffers
